VENTILATING, HEATING, AND HUMIDIFYING APPARATUS.

Application filed August 15, 1924. Serial No. 732,346.

My invention relates to improvements in apparatus for conditioning the atmosphere in a room by heating, ventilating and humidifying the same.

Qn robject is to provide an apparatus of the present nature, embodyinga. novel structure that is simple, durable, and relatively inexpensive and capable of efiiciently carrying/{out the purposes of the invention. 10 ore specifically it is my' object to provide a novel and eflicient arrangement of parts in an apparatus of the resent-kind, wherein a heating element may employed, not only as an air heater and circulation stimulator, but as an efiective humidifyingmedium as well. i v

With the foregoing and other objects in view, which will appear in the following description, the invention resides in the novel combination and arrangement of parts and i in the details of construction hereinafter described and claimed.

In the drawings, Fig. 1 is a vertical central sectional view of an apparatus em dying my invention; Fig. 2 is an end elevation thereof and Fig. 3 is a horizontal sectional view taken *on'thehneQ i-Bbf Figrl;

Reference being had to the rawings,

wherein similar reference characters havebeen used-throughout the several views to designate similar parts, it will be observed that my improvement includes two uprlght ducts A, B arranged side by side in a chamber C. The top of the duct A f lls short of the ceiling 10 of the chamber and the bottomof said duct falls short of the floor' 11 of said chamber. Said duct A has a damper 12 near the lower end thereof and is fitted with branch-ducts a, a just above 40 said damper 12. The branch-duct a" has communication with the outer air through the wall 13 oi the chamber 0 and is fitted with adamper 14. The branch-ducta opens into the chamber 0 and is also fitted with a damper, the same being designated by the numeral 15. The duct falls short of the a floor 11 at its lower end, the upper end of said duct being open to the outer air through the ceiling 10 of the chamber G.

Near the lower end of the duct 13 a damper 16 is fitted therein. Said duct B is supplied 'with'abranch-duct b near the ceil-' ing 10 of the chamber. This branch-duct b and the .duct B are respectively fitted with 58 dampers. 17, 18, the latter being located abovesaid branch duct. A drum-like base D w1th openings 19 at its lower margin, recomes the lower ends of said ducts A, B and supports a tank E through which said ducts pass. A valved filler pipe 20 supplies water 60 to this tank and a drain pipe 21 opening near the top of the tank E provides for the maintenance of the water level as shown in Flg. 1. Sand drain pipe 21 empties into the basin 22 m the floor 11 of the chamber, 6 which, 1n turn, empties into any convenient sewer or other drain as at 23..

Encircling that portion of the duct A surrounded by water in the tank E is a sleeve F. The body 24 of said sleeve F has an inner lining 25 spaced apart therefrom, the space between said body and lining being vacuous or packed, fluid tight, with a suitable -temperature insulating medium such as cork or the like. The inner surface of the lining 25 lies closely adjacent to that portlon of the duct A encircled by said linmg. Spacer legs 27 depending from the. lower edge of the sleeveF support said sleeve u on the bottom of the tank E with said 30 e ge slightly above said bottom, the legs 27 serving also to hold the sleeve in concentric "relation wlth respectto said duct A. The

upper margin of the sleeve bod 24, which a extends above the lining 25 is ormed with a series of aligned, horizontal openings 28 in the plane of the water level in the tank E. Thus it will be understood that the restricted space between the sleeve lining 25 and the duct A is open at the bottom of the sleeve F into the bottom of the tank E and at the top of said sleeve into'said tank at the 'water level therein.

Hung within the duct A are a number of electrical heating elements G of conventional type, the same being joined at their ends by s acer mountings 29 in the form of rings. angers 30 reaching upward from the upper ring 29 are hooked at their upper ends as at 30 andlcaught over the upper edge of the duct A (Fig. 1). Said heatmg elements G heat the air wlthin the duct A and, being arranged near the wall of said duct, intensely heat, through said wall, the limited quantity of water in the restricted 5 -s ace between the sleeve F and conduit A.

eing thus heated'amgile evaporation of the water is accom lishe to meet the uire ments for humldification within the c amber. Extending above the up duct A, the'upper margin of t e sleeve body 24: directsthe rising vapor into the current r end of the I of air circulated upwardly: in the duct 4X through the eflect of the heating elements G therein. The water in' the restricted space between the' sleeve F and duct A being in communication at the top and bottom of said sleeve with the larger quantity of water in the tank, a circulation of the water is set up through said restricted'space. Due t'o'thls circulation the duct B is substantially heated by the water, the efiect'thereof being to raise the temperature of. the ir' within said duct and thereby stimulate 1ts the air therein. Said air thus heated in duct B rises in said duct whereby is caused the egress of air from the lower portion of the chamber to the outside. Thus, it will be seen that the apparatus operates effectively to ventilate, heat and humidity the atmosph'ere within the chamber. Relative adjustment of the various dampers additionally results in a variously mixed ventilation. and internal circulation as will be readily understood. For example, in" addition to opening the dampers 14, 16 an'd18, the user may open case were damper 15. In this event and according to the relative adjustments of said dampers,

more or less of the air is recirculated inihe I and thetemperature of air w1thm-said-ductw room, some of the air at the lower portion of the room being drawn into branch duct a": and expelled into the upper portion'of the room from duct A, instead of being limited to entr I amper '15 tojbe closed. This practice of recirculating air is desirable when it is necessary to conserve heat. In

fact, ventilation may be avoided entirel and the device employed solelyior heate internal, circulation. This'efl'ect is obtained by closing dampers 14 and 18,; leavin damper 15 open. And-to augmentthis e fe'ct, dampers 16 and 17 .may be opened, in which event there is an upward movement of air in duct'B from the lower portion of the room to the upper portion thereof. Alsov the dampers 17 and 18.1

' it will; be understood that. the skimmingof.
